?

Add column by column; start from the column on the right.

Add the digits in the ones column:

8 + 7 + 0 = 15

How did we add the digits? Explanation below.

Group the ones together in order to make tens:


8 + 7 + 0 =


8 + 7 =


8 + 2 + 5 =


8 + 2 + 5 =


10 + 5 =


15


Change the order in which the numbers are added, the sum stays the same.

Answer:
918 + 1,927 + 490 = 3,335

The initial operation has become:

918 + 1,927 + 490 - 268 =


3,335 - 268

Now subtract the final numbers above:
3,335 - 268 = ?

Method used below: column subtracting, from right to left (traditional)


Stack the numbers on top of each other.

The ones digits line up in the first column from the right.

The tens digits line up in the next column to the left.

And so on...


 3335
-  268

?

Subtract column by column; start from the column on the right

Subtract the digits in the ones column:

5 - 8 = ?

The second digit is larger than the first.
Borrow from the next column to the left.

The borrowing is a two step process:


Subtract 1 from the top digit in the column of the tens: 3 - 1 = 2.
Cross out the top digit you've borrowed 1 from: 3.
Write the answer above that digit: 2.


When borrowing, 1 ten = 10 ones.
Add 10 to the top digit in the column of the ones: 10 + 5 = 15.


   2 
 33315
-  268

     

After borrowing, the subtraction has become:
15 - 8 = 10 + 5 - 8 = 10 + 5 - 8 = 5 + (10 - 8) = 5 + 2 = 7.
7 is the ones digit.
Write it down at the base of the ones column.

Subtract the digits in the tens column:

3 2 - 6 = ?

The second digit is larger than the first.
Borrow from the next column to the left.

Subtract 1 from the top digit in the column of the hundreds: 3 - 1 = 2.
Cross out the top digit you've borrowed 1 from: 3.
Write the answer above that digit: 2.


When borrowing, 1 hundred = 10 tens.
Add 10 to the top digit in the column of the tens: 10 + 2 = 12.

-  268

    7

After borrowing, the subtraction has become:
12 - 6 = 10 + 2 - 6 = 10 + 2 - 6 = 2 + (10 - 6) = 2 + 4 = 6.
6 is the tens digit.
Write it down at the base of the tens column.

Subtract the digits in the hundreds column:

3 2 - 2 = 0.
0 is the hundreds digit.
Write it down at the base of the hundreds column.
